The Ford Escape is equipped with two oxygen sensors, both serving its four-cylinder engine. One sensor is located in the exhaust system before the catalytic converter and the other is positioned after it. The sensors are easily identifiable as they are threaded into welded bungs on the headers and exhaust system. Their main function is to monitor the exhaust emissions from the engine to ensure the proper air-to-fuel ratio. A malfunctioning sensor can result in rough engine performance due to incorrect fuel or air levels. Replacing an oxygen sensor is a relatively straightforward task and typically costs less than $100 if replacement is necessary.
I notice there are 2 sensors positioned towards the engine, not after the catalytic converter, correct? I have a fault code for the sensor on bank 1, is that referring to the top sensor?
There are four sensors in the 3.0 V6 engine.
The Ford Escape is equipped with a pair of oxygen sensors.
My diagnostic tool shows that I have 4 codes, with 2 being positive and 2 being negative, but I'm having trouble figuring out how to sort them.
Best of luck! I tried for 7 hours to locate a component following a YouTube tutorial but had no success 😠 AutoZone mentioned it's in the middle top compartment. Let's find out, shall we?
In a 2004 Ford Escape, there are four O2 sensors – two lower and two upper ones. When I called an auto parts store to buy them, they asked if I needed the low or upper ones. I didn't check with the mechanic beforehand. Should I replace all four sensors or just the ones needed?
I don't have one to share with them yet.
